Recently, we developed a new class of ionic liquids, the so called Tuneable Aryl Alkyl Ionic Liquids (TAAILs). The use of ionic liquids in biphasic catalysis allows the recovery of the precious catalyst and prevents a contamination of the product. Ideally simple metal salts are sufficient, instead of expensive and complicated ligand systems.We present a new catalytic system based on TAAILs in combination with different platinum species for the hydrosilylation of various 1-alkenes. In our study we focused on the recyclability of the catalytic system, the reduction of by-products and the influence of the ionic liquid�s structure. As a benchmark we used the Karstedt catalyst, the common industrial standard. We also compared our results to 1-Butyl-3-methyl-1H-imidazolium bis(trifluoromethylsulfonyl)imide as a representative for a commercially available ionic liquid.
